The truck is the assembly at the very top of a flagpole — the housing that holds the pulley and supports the ornament (the ball or eagle on top). When your halyard frays, the pulley wears out, or your flag keeps wrapping around the pole, the truck is usually the part that needs replacing.
This is our Premium cap-style rotating truck, built for external halyard in-ground flagpoles. It's the heavier-duty version of our standard truck — cast aluminum housing with stainless steel ball bearings rated for continuous rotation under load, designed to last decades on a residential or commercial pole.
Critical Sizing — Read Before Ordering
Truck size must match your pole's top outside diameter. The most common return on flagpole hardware is a size mismatch — measure first, order second.
Cap-style trucks slide over the top of the pole and tighten with three set screws. The truck's inner diameter must match (or be slightly larger than) your pole's top outside diameter.
Available sizes:
1.875–2" Premium Cap-Style Truck — fits residential and light commercial poles with a 1.875" to 2" top OD
2.375–2.5" Premium Cap-Style Truck — fits mid-size commercial poles with a 2.375" to 2.5" top OD
3" Premium Cap-Style Truck — fits larger commercial poles with a 3" top OD
To measure: use calipers or a flexible tape around the very top of the pole (the narrowest point of a tapered pole). Round to the nearest 1/8". If your pole is between sizes, contact us — we'll help you confirm the right fit before you order.
What "Cap-Style External Rotating" Actually Means
Three distinctions, each one a real fit issue if you get it wrong:
Cap-Style (this truck)
The truck slides down over the top of the pole and clamps with set screws. Used on most tapered residential and commercial in-ground poles. If your pole has a tapped top with female threads directly in it, you probably have a spindle-style setup instead — those use a different truck. Our Deluxe Single-Pulley Revolving Truck is the most common spindle option.
External Halyard
The halyard rope runs on the outside of the pole and ties off at a cleat near the base. If your halyard runs inside the pole through an access door at the bottom, you have an internal halyard system, which uses a different truck design. Internal halyard systems vary widely by pole manufacturer — contact us with your pole make and model and we'll point you to the right replacement.
Rotating
The pulley assembly is mounted on stainless ball bearings that allow the entire halyard arrangement to rotate freely around the pole as wind shifts. This is what prevents the flag from wrapping around the pole — the #1 reason customers replace a stationary truck with a rotating one.

What Pairs Well
Halyard (5/16" Recommended)
Replacing a truck is the right time to replace the halyard rope too. Browse halyard options.
Ball or Eagle Finial
The 1/2"-13NC threading accepts any standard outdoor ball or eagle ornament. Browse outdoor finials.
Cleat and Snap Hardware
A new cleat for tying off the halyard and a fresh pair of flag snaps complete the refresh. Browse cleats and flag snaps.
Installation Overview
Replacing a truck is a straightforward job, provided you can safely access the top of the pole.
You'll need
Safe overhead access to the pole top — typically a bucket truck or lift
A wrench or hex driver for the set screws
A second person on the ground to manage the halyard
A new halyard, ornament, cleat, and snaps if you're refreshing the whole top assembly
Procedure
Lower and remove the flag.
Untie the halyard from the cleat at the base of the pole. Pull one end up and through the old truck's pulley to free the rope.
Remove the existing truck assembly from the pole.
Seat the new Premium truck over the top of the pole until it's fully down with no gap between the truck and the pole.
Tighten the three stainless set screws evenly. Snug, not crushing — overtightening can deform the truck or score the pole.
Thread your halyard through the new pulley and tie off at the cleat.
Thread a new ornament into the 1/2"-13NC top drilling and snug with a wrench.
Plan to replace the ornament too. Existing ball and eagle finials almost never come off cleanly — they're typically corroded, weather-fused, or threaded into a truck you're discarding. Order a replacement outdoor finial along with the truck so you're not stuck mid-job.
Don't work on a pole in wind, and don't work alone if you can avoid it. A swinging halyard or a dropped tool from height can cause serious injury.
Made in the USA
This truck is cast and assembled in the United States. We carry it specifically because the build quality holds up against imported alternatives that wear bearings within a season or two. Read more about our commitment to American-made products.
Frequently Asked Questions
What is a flagpole truck and what does it do?
The truck is the assembly at the top of the pole that houses the pulley for the halyard and provides the threaded mounting point for the ornament. It's what allows the flag to be raised and lowered, and on rotating models it prevents the halyard from wrapping around the pole.
What's the difference between cap-style and spindle-style trucks?
Cap-style trucks slide over the top of a hollow tapered pole and tighten with set screws. Spindle-style trucks mount onto a fixed spindle that protrudes from the top of the pole. They're not interchangeable — pole top design dictates which one you need. If you're not sure, contact us with photos of your pole top and we'll help you identify it.
What's the difference between rotating and stationary trucks?
A rotating truck has internal ball bearings that let the pulley assembly spin freely around the pole, so the halyard and flag follow the wind direction instead of wrapping around the pole. A stationary truck holds the pulley in a fixed position. If your existing flag wraps frequently, switching to a rotating truck usually solves it.
How do I measure my pole's top outside diameter?
Measure the very top of the pole — the narrowest point on a tapered pole — with calipers or a flexible tape. Round to the nearest 1/8". The truck size must match this measurement. The three available sizes are 1.875–2", 2.375–2.5", and 3".
What halyard diameter does this truck use?
The pulley is sized for 5/16" halyard. Larger diameters won't seat properly in the pulley groove; smaller diameters will work but may slip. We recommend replacing the halyard at the same time as the truck.
Will any ornament fit?
The top drilling is 1/2"-13NC, which is the standard U.S. flagpole ornament thread. Any standard outdoor ball or eagle finial will thread directly in. Some commercial poles use non-standard threads — if you're uncertain, contact us.
Can I install this myself?
Yes, with the right equipment. You'll need safe access to the top of the pole (typically a bucket truck or lift), basic tools, and a helper on the ground.
Questions?
We carry trucks, halyards, ornaments, and the rest of the hardware to refresh your flagpole top — and we're happy to help you identify what you have and what you need. Use our contact form and we'll get back to you with a recommendation.
